ESP32 LoRa Gateway: can't find port

ESP32 LoRa Gateway. Arduino 1.8.3. High Sierra. I’ve followed the install tutorials. The board will not show up in the Ports list.

No amount of RESET/PIN 0 button pressing/unplugging/replugging will help (if those buttons are supposed to do something, SF needs to clarify their tutorial).

Under System Information → USB, “USB2.0-Serial” shows up when I plug the module in. Of course, I’ve tried different cables. My computer never has problems with other boards. I did try plugging it into a Windows machine and that ended in a device install death spiral (but that’s probably another problem altogether…).

The board has worked in the past.

Anyone know how to fix this problem?

Agree. I can’t get this board to connect for the life of me. The buttons don’t even appear to do anything.
